Optimizing tilt angle for enhanced solar panel efficiency: A case study in Parkent, Uzbekistan

The efficiency of photovoltaic (PV) systems is significantly influenced by the tilt angle of solar panels, especially in regions with varying solar insolation across seasons. This study investigates the optimal tilt angle for a 10 kW solar-powered system installed in the Parkent district of Uzbekistan, a region characterized by a continental climate and high solar irradiance. Based on empirical formulas, the research identifies 33° as the fixed optimal tilt angle for year-round operation. Seasonal adjustments offer marginal gains, with two- and four-season tilt configurations improving performance by up to 4%. The findings highlight the importance of site-specific tilt optimization in maximizing solar energy harvesting, which is particularly relevant for autonomous renewable energy systems used in hydrogen production.
